PROCESS AND APPARATUS FOR PAPEBING PRESSED CLOTH OR THE LIKE.

Application filed February To all whom it may concern Be it known that I, HERMANN KRANTZ, a subject of the King of Prussia, residing at Aachen, No. 2 Monheimsallee, in the Kingdom of Prussia, Empire of Germany, have invented certain new and useful Improvements in a Process and Apparatus for Papering Pressed Cloth or the like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7 I

In order to give cloth a uniform luster and finish, it is usual to fold the strip from the bolt in a so-called whole width manner by means of lifts and to insert press-papers between the alternate zig-zags. The column of cloth then is carried from the lift into the press and pressed. During this manipulation the portions of cloth located outside of the edges of the press-papers remain unpressed. Heretofore, in order to make these unpressed folded portions even and bright also, the preliminarily pressed column of cloth was always returned to the lift again, then completely unpapered and thereupon repapered; that is to say, the cloth was taken from the lift, the press-papers were entirely taken out and restacked, and, when the cloth was refolded on the lift a second time, they were unstacked and returned in such a way that the heretofore unpressed spots of cloth would be covered. The column of cloth thus completely rebuilt and repapered was then bodily carried again into the press and ressed. I

The primary object of this invention is to devise a method and apparatus whereby there will be no need for completely unpapering and restacking the papers and the cloth as a preliminary to the preparatlon of the repapered pile which has been prepared for the second pressing operation. In other words, my invention contemplates the elimination of certain heretofore unavoidable steps between the first and the second ressing operation. 7

Other objects will be in part obvious from the annexed drawings and in part indicated in connection therewith by the following analysis of this invention.

This invention accordingly consists in the features of construction, combinations of parts, and in the unique relations of the Specification of Letters Patent.

members and in the relative proportioning and disposition thereof; all as more completely outlined herein.

To enable others skilled in the artso fully to comprehend the underlying 1 features thereof that they may embody the same by the numerous modifications in structure and relation contemplated by this invention, drawings. depicting a been annexed as a part of this disclosure, and in such drawings, like characters of reference denote corresponding parts throughout all the views of which Figure 1 diagrammatically represents an apparatus for carrying out the rebuilding of the column. Fig. 2 shows the apparatus combined with means for initially building the column, and Figs. 8 to 8 show successive steps in the operation of my method.

The manner in which my method is carried out may be best understood by referring to Figs. 8 to .8 inclusive. In these figures, A indicates a column of cloth and papers which has just been received from the press and in which all portions of the strip of cloth have been properly pressed, with the exception of the externally protruding folded margins, indicated by a, b, 0, etc. The portions of the cloth indicated by a, b, 0, etc., have been properly pressed and finished by reason of their interleaving relation with the papers, but their folded line portions. have, of course, not been subjected to the action of the press and therefore are not properly finished, so that it becomes necessary to resort to a second pressing operation during which these folded line portions are in interleaving relation with the papers. This can only be accomplished by a rebuilding of the pile or column, but by my method this building is accomplished far more easily than according to the old practice.

In carrying out this method, the column A, which is mounted on a suitable platform B, is rebuilt, layer by layer, on to an adjacent'support B so as to form a column A in which the folded lines of the cloth occupy an interleaving relation with the papers.

Fig. 3 diagrammatically represents the parts at the beginning of my operation or transference. The first step consists in swinging or otherwise shifting the top layer a; of cloth on to the table B in such a manner that the unpressed region a may be brought into interleaving relation with the preferred form have to. dropuntil the papers, This may be done by causing the end of the portion a to occupy a position shifted with relation to its original position on the table B, as shown best by Fig. 4:. The paper or board 10 between layers a and b is then superimposed on the portion a, and the board 11 is now shifted directly over the support B to the position shownby Fig. 5, and during this transposition the cloth will shift sufliciently with relation to the board 11 so as to locate the unpressed regions a and Z) intermediate the ends ofthe board. Thereupon, the boards 12 and 13- may, as indicated by Figs. 6 and 7, be swung over to occupy thev position shown by Fig. 8, and this operation may be continued until the entire original column has been unbui-lt, and simultaneously the secondary column A has been formed,- all Without involving a sepa rate piling and unpiling of'the boards and of the cloth, as has heretofore been the practice. It will be perceived that this method is expeditious and is accomplished with a minimum amount of'eifor't, and it possesses the special pronounced advantage that there is but little loss" of heat, which is an important item by reason ofthe fact that this heat isgenerated electrically and is therefore obtained at a comparatively high cost.

In carrying out the operations as above specified,- this invention furthermore contemplates a relative movement ofthe tables B B in such way that the uppermost layersof the columns A and A will always be maintained at substantially the same level; and this is essential because otherwise difficulty would be had with the cloth strip in causing the un'pressed portions thereof to be brought into correct interleaving relation.

s a means instrumental in enabling this progressive relative movement to be had of the tables B and B,- and further toenable the column readily to be carried to the press when it isready for the pressing operation, this: inventionroposes an apparatus comprising two lifts, l and 2, actuated hydraulically or otherwise and supporting tables or platforms B and B at their upper end' sx By setting theselifts in operation simultaneously, the one will be caused to rise slowly and the other may be caused to drop slowly at the same rate, so that the upper levels of the columns A and A will be maintaine'd'inabout the same relation. The column A- will preferably come from the press on a truck 3 which will pass over a suitable t'rackway sothjat it may be rolled in to the table B;

upper end of the column A is about level with a truck 7 mounted on the tableiB whereupon the processof transferring. the column from the one to the other will proceed tion of. the operation, the: table B" will be lowermost and the table B This table is then causedas indicated? At the comple-' uppermost whereupon the lift 2 may be elevated andthe truck 7 may be rolled over its trackway to the press in which the cloth receives its second pressing operation.

Fig. 2 shows the apparatus of Fig. 1 combined with means for initially building the first column A. In this case, the unpressed cloth is brought to the apparatus by means of a truck 9 and the cloth is passed over the overlying rollers, shown by Fig. 2, so that its end may be placed on the table? The cloth is then folded zig-z'ag, and on each fold a paper 5 will be inserted, and, occa sionally, an electrical heating element 6' will be interleaved, and while this is beihgaccomplished the table B will be gradually lowered and the table 8 will be gradually raised to keep the surfaces in the most convenient position. In this way,- the column A is prepared for a first pressing and as soon as it is built up, the lift 1 rises to enable the truck 3 to be rolled on to its track and taken to the press, as will be understood.

IVithout further analysis, the foregoing will so fully reveal the gist of this invention that others can by applying current knowledge readily adapt it for various ap p'lications without omitting certain features that,- from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and therefore such adaptations should and are intended to-be comprehended within the meaning and range-of equivalency of the following claims. 7

Having thus revealed this invention, I claim as new and desire to secure the following combinations of elements, or equiva-' lents thereof, by Letters Patent of the United States 1. A method of rebuilding an interleaved cloth column which comprehends placing the column onafirst platform; arranging asec- 0nd platform at about the same level as the upper end of the column; laterally shifting the successive layers-of the column on to the second platform to build up a substitute column thereon; and causing the platforms to move relatively to maintain the upperlevels of the original and substitute column at approximately the same level throughout the operation.

2. A method of rebuilding an interleaved cloth column which comprehends placing the column on a first platform; arranginga second platform at about the same level as the upper end of the column; laterally shift ing the successive layers of the column onto the second platform to build up a substitute column having the fold lines arranged-inter mediate the sides thereof; said rebui'ldingbe ing effected by alternately interleaving the cloth an d thepres's boards" while at the same time cai'1sing -the platforms to move'relatively' to maintain the upper levels of-' the original and substitute column at approximately the same level throughout the operation.

' 3. Means for building and rebuilding an interleaved cloth column combining a shortstroke lift adapted to support apile of interleaving elements; a transportable support adapted to carry a column of folded cloth; and a pair of oppositely movable long-stroke elevators located between said lift and said support, one of said elevators being independently depressible in conjunction with an uprise of said lift to initially build an interleaved cloth-column, and being subsequently adapted to rise during a corresponding depression of its companion elevator for aid in rebuilding said interleaved column.

4. A device of the class described, for rebuilding an interleaved cloth column, comprising a platform for supporting the column to be rebuilt, a second platform for supporting the column to be built from the first column, and means whereby said platforms are vertically movable relatively to each other to maintain the top surfaces of the two columns substantially in a common level during the rebuilding operation.

5. The herein disclosed process of rebuild- Gopies of this patent may be obtained for five cents each, by addressing the ing an interleaved cloth column, which consists in laterally shifting the successive layers of the column, with the press-boards still interfolded, and disposing said layers one upon the other so as to build a substitute column having the fold lines of the cloth arranged intermediate the sides of the sub stitute column.

6. The herein described process of rebuilding a cloth column made up of successive layers of cloth folded back and forth upon each other with press-boards interposed between the layers, which consists in shifting the press-boards with regard to the respective adjacent fold lines of the cloth and simultaneously shifting the pressboards along with the adjacent layers of the cloth laterally from the column to dispose the same in position to build a substitute column in which the fold lines of the cloth are arranged intermediate the sides of the substitute column. s

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
